Case insensitive string comparison with casecmp?

I found out today that Ruby has a casecmp? in the String class that compares strings case insensitively:

"Hello".casecmp?("hello") #=> true
"JAX".casecmp?("jAx")     #=> true
"foo".casecmp?("bar")     #=> false

This is preferable to string_1.downcase == string_2.downcase since it avoids allocating new string objects.
